Fuels - Combustion Air and Flue Gases

The exact value for your fuel can be obtained from your local natural gas distribution utility. Perfect combustion of natural gas requires approximately 9.5 scf of air per scf of natural gas and results in approximately 10.5 scf of products of combustion. The values vary somewhat depending upon the natural gas composition.

As the graph above suggests (note that there is no scale on the vertical axis), a gas or liquid fuel burner generally balances losses by operating somewhere between 105% to 120% of theoretical air. This is commonly referred to as operating with 5% to 20% excess air. Sensors Should be Fast, Cheap and Easy

Feb 13, 2020 · The first step to understanding how to cut down on burner energy costs is to understand what an air-to-fuel ratio is. Simply put, an air-to-fuel ratio is the measure of air compared to fuel involved in the combustion process. For safety reasons, knowing what the air-to-fuel ratio curve is on your burner system is critical. This curve measures the lowest amount of excess air that can be in the flue gas …

process. The primary measurements required under the Boiler Area Source Rule are flue gas oxygen content and flue gas carbon monoxide content at the high-fire or typical operation load. a) Examine the combustion control components (i.e., the system controlling the air-to-fuel ratio) and ensure it is functioning properly.
